The Great Orion Nebula (Tom Gray)

The Great Orion Nebula

Revision title: From dust to stars

A pleasing field of view with my 80mm semi-APO, operating at a focal length of 200mm, using an old SCT 0.6x reducer. A combination of RGB exposures from my 183C OSC, were aligned and stacked in Nebulosity, then processed in Startools. I may have over-stretched this a little, resulting in some halos around the brighter stars, and the moon interfered in the early part of the night. Tracking was good on my little Star Adventurer mount, with guided 2m exposures. The capacity of this little mount never ceases to amaze me, and it is so portable and quick to set up (almost like having my own observatory... almost).

Title: Extra deconvolution, extra detail

Description: Deconvolution drives up the detail and adjusts for atmospheric and optical aberrations, but can introduce artifacts

Title: Post-processed in SiRIL

Description: Another go at this Great Nebula. Pre-processed in Nebulosity, then to SiRIL for colour calibration, background extraction, SNCR reduction and deconvolution. Final smooth and denoise with GreyCstoration.

Title: Cross your eyes

Description: If you like a challenge - relax your eyes and move the image close to your eyes until you see 3 images, them move it slowly out, concentrate on the middle image, allowing your eyes to cross 👀, until it pops into focus - you'll get a nice 3D effect. PS do T stare too long or you’ll get a headache 🤕.

Title: From dust to stars

Description: Over-exposing the core shows off the wonderful dust and molecular gas that surrounds the Orion nebula - one can almost imagine it being sucked in, compressed and ignited into a new generation of stars

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
